Photos taken in portrait are being saved in landscape

Question

I've been trying to use the Android ACTION_IMAGE_CAPTURE intent and ACTION_GET_CONTENT intent to either take a photo or pick one. The problem I'm having is that when I when I try to take a photo using the Android photo intent in portrait mode, it saves it in landscape orientation.

I'm trying to save the Bitmap of the correctly orientated photo from a URI string.

I found this question: Android Camera Intent Saving Image Landscape When Taken Portrait , which is the exact same problem I'm having, but the answer is incomplete and didn't work for me. For example, what is the resizedBitmap , opts , and is file Uri.getPath() ?

Answer 1

Well some cameras lock the landscape mode as default mode of camera(Samsung note 2) so if you take a picture in potrait mode the image is still saved in landscape mode. Most of the camera will add metadata into the image like the camera vendor, model,etc. Amongst various metadata that can be present the one we are intrested in is the rotation data. It specifies by what degrees the image is to be rotated. For knowing the rotation you can use ExifInterface class.

resizedBitmap Images are stored as bitmap objects in android. As an image can be large loading them whole into memory can lead to outofmemory error's and make your app consume more memory. So a bitmap is first resized to appropriate size and then loaded into memory.

opts By opts you must be referring to BitmapFactory.Options method. It is a class that provides methods to change the behaviour of bitmaps like making it mutable(is set to true you can apply effects like grayscale to this bitmap) , find its height and width in pixels without loading it to RAM,etc.

file Its a class used to perform CRUD operations in any file stored in the system.

Uri.getPath() this method returns the path where your image is stored or null.
